' f Application fued rune` 1e, 1902# To @ZZ whom it wma/"concern: Y

Be it known that I, FRANK SOLEY, a citizen of the United States, residingin Philadelphia,

Pennsylvania, have invented certain Improvements in Padlocks, of which the following is a specification.

The object of my invention is to construct asimple and efficient fo'rm of master-key padlock, an object which I attain in the manner Io hereinafter set forth, referencebeing had to the accompanying drawings, in which- Figure 1 is a face view of my improved mas-4 ter-key padlock with the front cover-plate removed and showing the shackle closed and locked. Fig. 2 is a similar view showing the shackle unlocked by the action of the special, key. Fig. 3 is a similar view showing lthe shackle unlocked by the action of the masterkey. Fig. 4 isa perspective view of the vazo rions wards and tumblers of the lock. Fig. 5 is a View of the special key for the lock, and Fig. 6 is a view of the master-key. i

The lock-casing 1 is constructed in the usual manner of flanged plates held together by transverse studs 2, 3, 4, 5, and 6, the ends of which are riveted down upon or otherwise secured to the plates of the lock. The lock-cas` ing also carries the usual transverse key bearing or barrel 7, suitably mounted in the plates 3o of the casing, so as to be free to rotatetherein.

The-shackle 8 is pivoted to the transverse stud 5 of the lock and has two'internal toes 9 and 10, the toe 9 being under control of the tumblers of the lock and the toe 10 being acted -upon by one arm of a spring 11, which passes around the transverse stud 2 and has another arm bearing upon the tumblers of the lock, so as to normally retain them in the locking position. (Shown in Fig. 1.)

The lock has in the present instance three tumblers 12, 13, and 14 and threetixed wards 15, 16, and 17, the tumblers being hung upon the transverse studs 6, so that they can swing thereon when acted upon by the key-bits, but the wards 15, 16, and 17 being held in stationary position within the lock by engagement with the studs 3 and 6, said wards being so shaped as to require a particular bitting 15, 16, and 17a of the special key 18 of the 5o lock, but having no iniiuence upon the mas- Serial No. 111,905. (No model.)

ter-key 19. The tumbler 12Vh'as a projecting pin 20, which enters slots 21, formed in the tumblers 13 and 14, and the latter tumblers can be actuated either directly by the bits 13a 141l of the special key 18 or indirectly through the medium of the tumbler l2 and its pin 20, said tumbler 12 being actuated by the bit 12a of the master-key 19. Normallythat is to say, when the shackle of the lock is closed-the toe 9 of said shackle is engaged by the tumblers 13 and 14, and the shackle is thereby retained in the closed position; but if said tumblers 13 and 14 are acted upon by the bits 13a 14a of the special key 18 they will be withdrawn from engagement with the toe 9 of the shackle, so as to permit of the opening of The latter by the action of the spring 1l, as shown in Fig. 2. The provision of the slots 21 permits such movement of the Atumblers 13 and 14 without of necessity imparting any movement to the tumbler 12, although, if desired, said tumbler may have such connection with the tu mblers 13 and 14 that no lost motion of either is permitted. When the lock is opened by the action of the master-key upon the tumblen1-2, the engagement ofthe pin 20 of the latter with the tumblers 13 and 14 causes such'movement of said tumblers as to release the shackle, as shown in Fig. 3.

It is immaterial to the main purpose of my invention which part of the shackle is engaged by the tumblers, and it is also matt-er of indifference whether the shackle is retained by engagement with a master-key tumbler or tumblers or a special-key tumbler or tumblers, so long as there is provision for causing the non-engaging tumbler or tumblers to impart movement to the engaging tumbler or tumblers.

While I have shown the use of two turnblers for the action of the special key, there may be but one of. said tumblers or more than two, and where a number of tuin blers are employed the fixed Wards may be omitted.

Having thus described my invention, I claim and desire to secure by Letters Patent-.-

1. A master-key padlock comprising a casing with movable shackle, a master-key tum- IOO bler, a special-key tumbler or tumblers, one

of said tumblers engaging the shackle to hold it in the locked position and means whereby one tumbler or tumblers is actuated by the movement of the other tumbler or tumblers, substantially as specified.

2. The combination in a master-key padlock, of the casing, and the movable shackle, with a master-key tumbler, and a special-key tumbler, one of said tumblers engaging the shackle to hold it in the locked position, and a 10st-motion connection between the two, substantially as specified.

The combination in a master-key padlock, of a casing, a movable shackle, one or more fixed wards, a master-key tumbler, a special-key tumbler or tumblers, one of said 'rumblers engagingthe shackle to hold itin the locked position, and means whereby the movement of one tumbler or tumblers is imparted to the. other tumbler or tu mblers, substantially as specified.

4. The combination in a master-key padlock, of a casing, a.pivoted swinging shackle having two projectingtoes, a spring for acting upon one of said toes, special-key tumbler or tumblers and a master-key tumbler, one of which engages with the other toe of the shackle, and means whereby the movement of one tumbler is imparted to the other tumbler,

substantially as specified.

5. The combination in a master-key padlock, of a casing, a pivoted and swinging shackle having two projecting toes, special tumbler or tumblers and a master-key tumbler one of which acts upon one of the toes of the shackle to retain the same in the locked position, a spring acting upon the other toe to open the shackle, and also acting upon one or both ot' the tumbler or tumblers of the lock, and means whereby the movement of one tumbler structure is imparted to the other tumbler, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRANK SOLEY.'
